我需要制作联系人的多重列表视图，当我点击确认按钮时，应用程序应该将手机号码插入数据库。
listview片段代码是：
public class GestionContact extends AppCompatActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gestion_contact);
//Récupère le fragment permettant d'accèder à la liste des contacts
getSupportFragmentManager().beginTransaction().replace(R.id.fragmentLayout,new MonFragment()).commit();
}
我的活动：
@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css');
.multiBanner {
position: relative;
margin: auto;
top: 0px;
left: 0;

您可以按照此代码作为参考
ArrayAdapter adapter = new ArrayAdapter（this，android.R.layout.simple_list_item_multiple_choice，listContent）; myList.setChoiceMode（ListView.CHOICE_MODE_MULTIPLE）;
myList.setAdapter(adapter);
getChoice.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View v) {
String selected = "";
int cntChoice = myList.getCount();
SparseBooleanArray sparseBooleanArray = myList.getCheckedItemPositions();
for(int i = 0; i < cntChoice; i++){
if(sparseBooleanArray.get(i)) {
selected += myList.getItemAtPosition(i).toString() + "\n";
}
}
Toast.makeText(MainActivity.this, selected, Toast.LENGTH_LONG).show();
}});

当我点击按钮getChoice时，我想只接受numerotel 但现在需要名字和numerotel
像这样：
检索名称+号码的联系方式：
private List<String> retrieveContacts(ContentResolver contentResolver)
{
final Set<String> contacts = new HashSet<String>();
final Cursor cursor = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
if (cursor == null)
{
Log.e("retrieveContacts", "Cannot retrieve the contacts");
return null;
}
if (cursor.moveToFirst() == true)
{
do
{
final long id = Long.parseLong(cursor.getString(cursor.getColumnIndex(ContactsContract.Data._ID)));
final String name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
final String numerotel = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
final int hasPhoneNumber = cursor.getInt(cursor.getColumnIndex(ContactsContract.Data.HAS_PHONE_NUMBER));
if (hasPhoneNumber > 0)
{
contacts.add(name + " " + numerotel);
}
}
while (cursor.moveToNext() == true);
}
if (cursor.isClosed() == false)
{
cursor.close();
}
final List<String> sortedContacts = new ArrayList<String>(contacts);
Collections.sort(sortedContacts);
return sortedContacts;
}
OnCreateView：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{ View rootView = inflater.inflate(R.layout.fragment_gestion_contact, container, false);
final ListView list = (ListView) rootView.findViewById(android.R.id.list);
final List<String> contacts = retrieveContacts(getActivity().getContentResolver());
if (contacts != null) {
list.setAdapter(new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_multiple_choice, contacts));
list.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
getChoice = (Button) rootView.findViewById(R.id.getchoice);
getChoice.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String selected = "";
int cntChoice = list.getCount();
SparseBooleanArray sparseBooleanArray = list.getCheckedItemPositions();
for(int i = 0; i < cntChoice; i++){
if(sparseBooleanArray.get(i)) {
selected += list.getItemAtPosition(i).toString() + "\n";
}
}
Log.d("CONFIRMATION", selected);
}});
}
return rootView;
}
我只想选择数字+ = list.getItemAtPosition（i）.toString（）+“\ n”;
